Tape-based delay effect

Augustus Loop is an emulation of a tape-based delay effect, with some extra features to facilitate its use as a looping device :

- Really long maximum delay (3600 seconds - that's one hour).
- Tap tempo.
- Virtual tape. The delay simulates an old-style tape delay, meaning you can: change the tape speed (i.e. pitch up and down); reverse the tape direction; smoothly change the delay time (as if you were changing the head gap on a tape delay).
- Multimode filter and saturation in the feedback loop.
- Four feedback taps (left to left, left to right, right to left and right to right) with independent delay time and feedback settings, for ping-pong effects, stereo delays etc.
- Pitch and filter LFOs.

Fixed a keypress issue in certain VST hosts (plug-in would respond to numeric input but not to pressing Return).

Augustus Loop v 2.2.1Feb 25, 2010MacOS X UB

Issues addressed in this release:

Fixed compatibility with OS X 10.5.

Worked around a bug in Digital Performer 7.1 which would cause a crash when the plug-in prefs dialog was used.

Generally improved stability of the Cocoa UI.

Augustus Loop v 2.2.0Feb 10, 2010MacOS X UB

This is a milestone for Expert Sleepers as it's our first 64 bit release. Specifically it's a 32/64 bit Intel Audio Unit, and so can be used in native 64 bit mode in Logic 9 and Mainstage 2.1 when those hosts are running as 64 bit applications.

From now on we anticipate that all our Mac releases will be Intel only, will support 64 bit use, and will require Mac OS X 10.5 or 10.6.

There are no new features in Augustus Loop v2.2.0 other than the availability of a 64 bit variant. If you're not using 64 bit hosts, there's no reason to take this update.

Augustus Loop v 2.1.2Oct 7, 2009MacOS X UB

Compatibility with Mac OS X 10.6 "Snow Leopard"

Augustus Loop v 2.1.1Aug 30, 2009MacOS X UB

This version adds the new OSC functionality as recently added to Warbler and Silent Way for TouchOSC compatibility.

Augustus Loop v 2.1.0May 11, 2009MacOS X UB

V2.1.0 adds some new functionality to Augustus's MIDI/OSC and GUI scripting:

Timing functions

In MIDI/OSC scripts you can now
* get the time between two events
* ask for a function to be called after a certain amount of time, or regularly at a specified interval.

Using these functions you can do useful things like distinguish between short and long footpedal presses, or detect double taps etc.

GUI indicators for MIDI/OSC script status

A new form of the existing 'indicator' GUI item has been added, together with some corresponding MIDI/OSC script functions, to allow you to create GUI elements that reflect the state of scripted variables.

Augustus Loop v 2.0.4Apr 30, 2009MacOS X UB

This is an AU-only bug fix release. It addresses an issue where no audio would reach the fx loop outputs with certain combinations of parameter settings.

Augustus Loop v 2.0.3Mar 22, 2009MacOS X UB

V.2.0.3 improves the behaviour of parameter automation in Logic - specifically:
* the pitch buttons now cause automation to be recorded.
* the four delay time parameters (delay slider min/max, max delay and delay time) now use 'high resolution' mode automation.

Augustus Loop v 2.0.2Mar 5, 2009MacOS X UB

It addresses an issue with recording parameter automation in Logic Pro.

Augustus Loop v 2.0.1Jan 14, 2009MacOS X UB

* It is now possible to completely override the default MIDI/OSC script with a custom script. (Previously it was only possible to extend the functionality, not replace it.)
* Added a new preferences option, 'Ignore AudioUnitReset', which can be useful when using the AU version of the plug-in in a live context. See the manual for a fuller explanation.

Augustus Loop v 2.0.0Oct 26, 2008MacOS X UB

Augustus Loop's GUI is now fully skinnable and scriptable.

- MIDI behaviour is now scriptable.
- VST version now receives MIDI.
- Added Record Offset feature.
- Added waveform display.
- The 'Max Delay Time' parameter now has a smaller minimum value (1.0 seconds)
and is not rounded to the nearest 10 seconds.
- Added Tape Read Mode parameter.
- The Freeze Loop function is much improved.
- A small crossfade is now applied when activating Clear Loop, and when Clear Loop
ends.
- The Input Level parameter is now protected against sudden changes, which previ-
ously could result in audio artefacts. In particular this makes the Punch In/Out fea-
tures more usable.
- A small crossfade is now applied when activating Tap Record.
- Added a new mode for the Freeze Loop function, "Freeze Current".
- Added OSC support.
- Added 'Sync Group' feature.
- Added new 'Tape Sim' section.
- Added factory presets.
- Fixed a bug that could cause Digital Mode to not engage correctly.

Augustus Loop v 1.8.1Jul 20, 2008MacOS X UB

Fixed a problem where Augustus Loop's GUI would stop Logic's Key Commands from working.
Fixed an issue which could cause Apple's AU validation tool (as used by Logic) to run very slowly when validating Augustus Loop on OS X Leopard.

Augustus Loop v 1.8.0Jun 7, 2008MacOS X UB

* New 6-in 6-out configuration of the plug-in, allowing audio to be routed through external processing either side of the virtual tape.
* Fixed an issue that could cause a crash in Logic 8 when opening a song containing multiple instances of Augustus Loop with their GUIs open.

Augustus Loop v 1.7.2Mar 22, 2008MacOS X UB

V1.7.2 fixes an issue which would cause the VST version to crash if the AU version were not also installed. It also further improves the plug-in's resilience to font installation issues.

Augustus Loop v 1.7.0Mar 16, 2008MacOS X UB

First Windows version.
First Mac OS X VST version.
New GUI.
Fixed various filter problems. In particular, the filter cutoff was being limited to about 2kHz - now the full range up to 8kHz is usable. Therefore, this version may sound different to previous versions at the same settings. A preferences setting is provided to revert to the previous behaviour, which may be useful if you have to re-visit an old mix after upgrading.
Added 'Tape Stop' feature.

Augustus Loop v 1.6.5Oct 2, 2007MacOS X UB

V1.6.5 now responds properly to AudioUnitReset(), so in e.g. Logic the delay buffer will be cleared when song playback is started etc

V1.5.0 is a major update which adds a simple but very important feature - the ability to change the delay time without 'tape delay' inertia effects. This gives you loop multiply/divide capabilities, lets you tap the loop tempo without clearing it first, makes the 'Fix Delay' feature useful (in which the delay time stays constant as the pitch is varied) etc.

Added 'clear loop' function to wipe the tape.
Added auto fade-in/out envelope, with override and optional auto-clear of loop on fade-out completion.
Current loop length now displayed in host's bar/beat units as well as seconds.
Added auto punch in/out, quantized to loop length (seconds or host units) or host transport position.
Loop input level can be controlled by punch in/out.
Extensive CPU efficiency improvements.
Now correctly reports silent output to downstream processing, resulting in further efficiency improvements in hosts that support this feature.
Fixed potential crash when using Freeze Loop and Host Tempo.
Improved behaviour of Freeze Loop in conjunction with Reverse.
Maximum delay time is now limited according to installed system RAM

Fixed a keypress issue in certain VST hosts (plug-in would respond to numeric input but not to pressing Return).
